应用弹性波反射法无损检测桩身质量
Pile Quality Testing by Elastic Wave Reflection Technique
-
摘要: 本文从波动理论出发，阐明了桩身存在破损介面时波阻抗变化特征及反射波相位变化差异，结合工程实际分析对比提出判断桩身破损情况的办法。Abstract: Based upon the elastic wave theory, the characteristics of wave impedance and the features of reflection wave phase varying with the defect interface of a pile are described. Methods for estimating the defects of tested pile are proposed through analysis of practical cases.
